Hey guys, Few questions? Can mk 677 stunt growth in underage users? Can it prevent future muscle growth? Will it cause lethargy? Any outstanding sides? What type of benefits should I expect when running it solo?

The fact that you are asking about underage users make us believe you are underage. There is no advice we should give to underage on taking hormonal supplements except to stay away from them. So if you are underage, this product, which is a growth hormone secretagouge would be pointless as your growth hormone levels are already sky high.
